    24" Petzval?!

    Hi, all -

    So, I picked up a l-o-n-g Petzval - a 24" f/11 Beseler. No iris, no slots for stops. I'm left wondering what a lens like this was originally used for? Did they make Magic Lanterns that used a 24" lens? Would like to see that one...

    Beseler made some large Stereopticons (and ML's).... probably used in that capacity..

    In the good old days, every large lecture room at every University, everywhere, had a huge projection device (non-stealable) for large dias and the episcope function. They disappeared when OH projectors came in the early 60's.
